Assuming it comes to market, the Winkelvoss Bitcoin Trust, an ETF sponsored by twin brothers Cameron and Tyler Winkelvoss, will trade under the ticker “COIN,” according to a Form S-1 filing with the Securities and Exchange Commission.

In May, a regulatory filing revealed the Winkelvoss Bitcoin Trust will trade on the Nasdaq. The most recent filing shows no change to that plan. In February, the brothers formed the Winkdex, which will be used to price the value of assets held by the trust. [Bitcoin ETF Will Trade on Nasdaq]

It has been a year since the Winkelvoss brothers filed for the bitcoin ETF, underscoring the difficulty in launching a new ETF, particularly one for a non-traditional asset class such as bitcoin.

SecondMarket’s Bitcoin Investment Trust could beat its Winkelvoss rival to market. In fact, the Bitcoin Investment Trust has been available to accredited investors and has already amassed $70 million in assets under management. [The Bitcoin ETF You Haven’t Heard Of]
